Some time ago you guys helped me with some LED wiring. Thanks to you I now
have 24 Blue LEDs working above my Coral grow out tank. To control the
temperature of these tanks I use an electronic temperature controller to
switch on/off heaters. One works fine but I have another controller that
switches the power on all the time irrespective of the temperature. Both
controllers have a probe that senses the water temperature. I took the one
that is permanently on apart and the 'switch' is a T0805MH. With the
controller unplugged and using a digital multi meter there is no resistance
between any of the three wires. They all seem shorted together. Is this
normal? Just in case it is the T0805MH that is defective I have looked at RS
for a T0805MH with no luck. Is there an equivalent? I hope I have given you
enough info to help me. As I said before I am a marine biologist and know
nothing about electronics - well a little about LEDs ;-)
